IB Physics Heat and Internal Energy
/A tutorial sheet on the heat and internal energy follows.
- An system gains an amount Q of heat energy. Does the internal energy increase by this amount?
- An air conditioner extracts an amount Q of heat energy from a room. Is the work done by the air conditioner Q?
- A heat engine has a heat inflow Q1 per cycle and a heat outflow of Q2 each cycle. What is the efficiency of this engine?
- Must a heat engine always have a clockwise cycle on a p-V diagram?
- Does a heat pump always have an anticlockwise cycle on a p-V diagram?
